BACKGROUND Field of the Disclosure

This disclosure relates generally to the development of golf putting training device that teaches a golfer to start the putt/ball on a desired line of travel at the desired speed by providing the golfer with feedback on correct face angle, aim, acceleration, and/or related parameters.

Description of the Related Art

Many factors contribute to successfully putting a golf ball so that it travels along an intended putting line. The main factor is the face angle of the putter head at impact. The putter face can be “square”, “open”, or “closed” to the intended starting line at the time of impact with the golf ball. Because a putt's initial starting direction is greatly affected by the face angle of the putter head at impact, a small misalignment between the face angle and the intended putting line can cause a putt to miss a target by a significant margin. Another main factor is the velocity of the putter at the time of impact. Improper putter head velocity can result in putts that are short or long. For breaking putts (where the proper putting line to the hole is curved rather than straight), putter head velocity becomes even more important.

A large majority of golf putting training aids currently on the market are designed only to develop the path (or arc) on which the putter head travels during a putting stroke. Most other putting training aids are designed only to provide feedback on aiming the putter head (such as a string line) or determining whether the golf ball was struck in the center of percussion (the sweet spot) of the putter head (such as impact tape). Products currently on the market that attempt to train a square putter head at impact or to measure putter head velocity are scarce, and those few that do exist generally require attaching a device to the putter itself, and/or are prohibitively expensive for most golfers, and/or do not provide consistent detailed feedback on face angle at impact, and/or are ineffective outdoors, and/or must be manually reset after each putt.

Therefore, there is a need for a device that can train users to putt with proper face angle, velocity, centered impact, and proper alignment of the putter head. The device described herein can provide feedback to allow users to correct/adjust their swing to attain proper face angle, velocity, centered impact, and proper alignment of the putter head.

The foregoing and other features of the present development will become more fully apparent from the following description and appended claims, taken in conjunction with the accompanying drawings. Understanding that these drawings depict only several embodiments in accordance with the development and are not to be considered limiting of its scope, the development will be described with additional specificity and detail through use of the accompanying drawings. In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present development, as generally described herein, and illustrated in the drawings, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.

DETAILED DESCRIPTION

Most good putters utilize either a “pendulum” stroke where the speed of the putter head at impact is dictated by the length of the backswing (that is, not by muscular effort to accelerate the putt through impact), or a “pop” stroke, where a shorter backswing and muscular effort by the golfer are accompanied by very little follow-through of the putter head after impact. In either the “pendulum” stroke or a “pop” stroke, the putter head accelerates to its maximum at impact with a golf ball and then either “coasts” through the impact interval or stops shortly after the impact interval.

A physical barrier to the follow-through of the putter head can be effective to train both a “pendulum” and a “pop” stroke. A physical barrier helps train a “pendulum” stroke because the barrier limits extra acceleration after impact and focuses the golfer on proper backswing length, a smooth transition, and a “coasting” impact. A physical barrier helps train a “pop” stroke because the barrier teaches the feeling of a putter head stopping promptly after impact.

One critical element to consistent putting is proper alignment of the putter head to a desired starting line of the putt. The training aid device disclosed herein can use various sensors to determine whether the putter head is aligned or misaligned before impact. Additionally, the training aid device can include a simple adjustable straight-line rod that can provide feedback for face angle, backswing length and sweet-spot elements.

The proper speed of the putter head at impact is also important to making putts, especially breaking putts (that is, where the proper target line, or track, to the hole is curved rather than straight). Providing golfers with immediate visual read-outs of the speed of the putter head at impact can afford golfers with feedback on appropriate length of backswing and/or muscular effort to create particular putter head speeds for different lengths of putts. Although certain sensor feedback devices measure putter speed at impact, they generally require placing the device on the putter itself as opposed to on the actual putting surface.

Yet another important element to consistent putting is striking the center of the ball with the center of percussion (“sweet spot”) of the putter head. An off-center hit causes the putter face to twist, which can send the ball off the desired target line. Additionally, an off-center hit can lessen the transfer of energy to the ball, making distance control more difficult. The training aid device disclosed herein can include a visual reference that allows a user to compare the putter face and the training aid at impact so the user can see if the putter head was centered at impact.

Most great putters keep the head and lower body relatively still during the stroke, which promotes consistency in both the path and face angle of the putter. A common error is for the golfer to “look up” before completion of the impact interval, which in turn often causes alterations in the putter head path and/or face angle. The training aid device disclosed herein can include a sighting “shield” incorporated into a training aid that also provides feedback for face angle, backswing length and sweet-spot elements.

FIG. 1 is a schematic illustration of a training aid device 100. The training aid device 100 can be placed on different types of indoor and outdoor surfaces including, but not limited to, golf green, synthetic turf, carpet, and the like. The training aid device 100 may or may not be secured in place. In some implementations, the training aid device 100 can be placed adjacent to a golf ball 102. As a user starts his stroke to hit the ball 102 with a putter 104, a putter head 106 moves towards the ball 102 and the training aid device 100. As discussed above, the training aid device 100 can provide various information about the putter head including, but not limited to, putter head speed, putter head orientation, and the like.

With reference to FIGS. 2A-2C, the training aid device 100 can include a processor 200, a battery 202, a communication module 204, a sensor assembly 206, a display module 208, and a memory 210. The processor 200 can retrieve various instructions from the memory 210 to, for example, operate the sensor assembly 206, transmit various types of data using the communication module 204, generate display data and display the data using the display module 208, and the like. The processor 200 can draw power from the batter 202.

The memory 200 can store various types of instructions, as discussed above. Additionally, the memory 200 can also store data collected and/or generated by the sensor assembly 206.

The battery 202 can be disposable or rechargeable. The battery 202 can be coupled to the processor 200 via a switch 212. The switch 212 can have an “ON” position and an “OFF” position. When in the “ON” position, the switch 212 can be open and allow the battery 202 to provide power for the processor 200. In contrast, when in the “OFF” position, the switch 212 can be closed and prevent the processor 200 from receiving power from the battery 202.

The communication module 204 can allow the processor 200 to communication with different devices including, but not limited to, mobile communication devices, mobile display devices, and the like. The communication module 204 can establish one or more wired communications and/or one or more wireless communications with other devices. For example, the communication module 204 can include different types of ports including, but not limited to, PS/2 port, Serial port, Parallel port, HDMI, USB 2.0, USB 3.0, Digital Visual Interface (DVI), and the like. The communication module 204 can establish different types of wireless communications including infrared (IR) communication, microwave communication, Wi-Fi communication, Bluetooth®, Near-Field Communication (NFC), and the like. The communication between the communication module 204 and other devices can be one-way or wo-way communication.

The sensor assembly 206 can include one or more sensors that can collect data regarding the putter head. For example, the sensor assembly 206 can include a sensor 220, a sensor 222, and a sensor 224, as shown in FIG. 2C. It is contemplated that the sensor assembly 206 can include less than three sensors or more than three sensors. In some implementations, the sensor assembly 206 can include two sensors. In some implementations, the sensor assembly 206 can include four sensors, five sensors, 10 sensors, 15 sensors, and etc.

The display module 208 can show different types of information associated with the putter head 106 including, but not limited to, putter head velocity, putter head angular orientation (in other words, face angle), putter head acceleration, and the like. The display module 208 can display information in combination of numbers, letters, symbols, and the like. Additionally, the display module 208 can include a speaker that can provide the information in auditory form. For example, the display module 208 can provide visual and/or auditory indication whether the putter head 106 was “square” with the training aid device 100, “open,” or “closed” with respect to the training aid device 100. Additionally, the display module 208 can provide visual and/or auditory indication what the velocity of the putter head 106 was when it struck the ball 102.

The sensors 220, 222, and 224 can be used to measure the distance between the training aid device 100 and the putter head 106. Additionally and/or alternatively, the sensors 220, 222, and 224 can determine when the putter head 106 is positioned at a predetermined distance from the training aid device 100. The predetermined distance between the sensors 220, 222, and 224 and the training aid device 100 can be between about 1 cm (centimeters) and 30 cm, between about 2 cm and about 25 cm, between about 5 cm and about 20 cm, between about 10 cm and about 15 cm, or about 1 cm, 2 cm , 3 cm, 4 cm, 5 cm, 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, or between any two of aforementioned values.

In some implementations, the sensors of the sensor assembly 206 can have different predetermined distances. For example, the sensors 220, 222 can determine when the putter head 106 is 5 cm away from the sensors 220, 222, while the sensor 224 can determine when the putter head 106 is 10 cm away from the sensor 224.

Additionally and/or alternatively, some or all of the sensors may be able to take multiple sets of data during a swing of the putter head 106. For example, the sensor 220 may take a set of data to determine positions of the putter head 106 at multiple different times. By comparing at least a two different sets of data representing time and position of the putter head 106, velocity of the putter head 106 during a swing can be determined.

In some implementations, the data collected by the sensors during a swing of the putter head 106 can be used to graphically illustrate positions of the putter head 106 during the swing at different times. Additionally and/or alternatively, the data can be used to graphically illustrate velocity and/or acceleration of the putter head 106 at different stages of the swing. Such graphical illustrations may be displayed by the display module 208. In some implementations, such data can be transmitted to mobile devices via the communication module 204 and displayed by the mobile devices. Data collected by the sensors may be displayed in a table format and/or in a graph format.

The sensors 220, 222, and 224 can be aligned and/or positioned on a front surface 300 of the training aid device 100. The front surface 300 can be substantially flat and face the putter head 106 of the putter 104. The front surface 300 can be substantially vertical with respect to the ground. The front surface 300 can define an axis representing a desired putter face angle.

The front surface 300 can be a striking surface that comes into contact with the putter head 106. If, at the time of contact between the front surface 300 and the putter head 106, the putter head 106 is flush with the front surface 300, the putter head 106 was “square” with the training aid device 100, indicating that the putter head 106 was substantially aligned with the desired putter face angle. On the other hand, if, at the time of contact between the front surface 300 and the putter head 106, the putter head 106 is not flush with the front surface 300, the putter head 106 was not “square” with the training aid device 100, indicating that the putter head 106 was misaligned with the desired putter face angle. The front surface 300 can provide tactile response to the user when the putter head 106 strikes the front surface 300. The tactile response can indicate whether the putter head 106 was “square” with the training aid device 100. Depending of angular orientation of the putter head 106, its heel 800 or toe 802 (see FIGS. 8A-8C) can contact a first side of the front surface 300 before the other portion of the putter head 106 contacts a second side of the front surface 300.

The sensors 220, 222, and 224 can be positioned in different arrays/configurations as shown in FIGS. 3A-3F. As shown in FIGS. 3A-3C, two of the sensors 220, 222, and 224 can be positioned along a bottom portion of the front surface 300 while one of the sensors 220, 222, and 224 can be positioned along a top portion of the front surface 300. For example, the sensors 220, 222 can be positioned along a bottom portion while the sensor 224 can be positioned along a top portion. Alternatively, as shown in FIGS. 3D-3F, two of the sensors 220, 222, and 224 can be positioned along the top portion of the front surface 300 while one of the sensors 220, 222, and 224 can be positioned along the bottom portion of the front surface 300.

One of the sensors (for example, the sensor 224) of the sensor assembly 206 can be positioned above or below the other sensors (for example, the sensors 220 and 222). In some implementations, the sensor 224 can be positioned between the sensors 220, 222. The sensor 224 can be positioned directly between the sensors 220, 222. Alternatively, the sensor 224 can be positioned offset from the sensors 220, 222 as shown in FIGS. 3C and 3F.

It is understood that different configurations or orientations of the sensors 220, 222, and 224 may be used to collect data sufficient to calculate velocity and/or angular orientation of the putter head 106. As discussed above, different configurations or orientations of sensors can include less than three sensors, more than three sensors, more than five sensors, more than ten sensors, and etc.

With reference to FIGS. 4A-4D, the training aid device 100 can include a channel 402, a first base 450, a second base 460. The first base 450 can include a lateral support 454 and a rear support 452, and the second base 460 can include a lateral support 464 and a rear support 462. The rear supports 452, 462 and lateral supports 454, 464 can provide stability for the training aid device 100. The lateral supports 454, 464 can extend laterally with respect to the front surface 300 of the training aid device 100. In some implementations, the lateral supports 454, 464 can be coupled to the first base 450 and second base 460, respectively. The rear supports 452, 462 can extend rearwardly from the bases 450, 460, respectively.

The training aid device 100 can include one or more openings 404. The one or more openings 404 can be defined by the rear supports 452, 462, and lateral supports 454, 464. The openings 404 can be in different shapes including, but not limited to, circular, square, triangular, and the like. The openings 404 can be dimensioned to receive golf tees in different sizes and shapes. Additionally and/or alternatively, the openings 404 can receive other types of securing devices such as pins, rods, and the like.

The first base 450 and the second base 460 can be connected via a cover 422. The cover 422 can include one or more enclosures that can house the processor 200, the battery 202, the communication module 204, the memory 210, the sensor assembly 206, and the display module 208. In some implementations, the cover 422 can prevent the user from seeing a first portion of the roll of the ball 102 after being struck by the putter head 106. Having the cover 422 can prevent the user from looking up to see if the ball 102 is rolling towards the target. This can be advantageous because putter head path and/or face angle may be altered by user looking up to soon. Therefore, the cover 422 can prevent the user from looking up too soon and thereby possible altering putter head path and/or face angle.

The training aid device 100 can include a first body 406 and a second body 408 that can together define the front surface 300 of the training aid device 100. The first body 406 can be positioned left side of the device 100 and the second body 408 can be positioned right side of the device 100, and vice versa. The first body 406 can be coupled to the base 450 while the second body 408 can be coupled to the base 460. As discussed above, the training aid device 100 can be positioned on the ground such that the front surface 300 can face the putter head 106 as the putter head 106 moves towards the training aid device 100. In this regard, the first body 406 and the second body 408 can be facing the putter head 106 as the putter head 106 moves towards the training aid device 100. In some implementations, the first body 406 can correspond to a heel 800 (see FIGS. 8A-8C) of the putter head 106 and the second body 408 can correspond to a toe 802 (see FIGS. 8A-8C) of the putter head 106 (for a right-handed user).

In some implementations, the first body 406 and the second body 408 of the training aid device 100 provide tactile response to a user's swing of the putter 104. As the putter head 106 strikes the ball 102, the putter head 106 can make contact with the front surface 300. Alternatively, the putter head 106 can make contact with the front surface 300 after hitting the ball 102. Depending of angular orientation of the putter head 106, its heel 800 or toe 802 can contact either the first body 406 or the second body 408 (see FIGS. 8A-8C).

The first body 406 and the second body 408 can be surfaces that are flush with the front surface 300. In some implementations, the first body 406 and the second body 408 may not be flush with the front surface 300 and protrude from the front surface 300. The first body 406 and the second body 408 can be raised surfaces. The first body 406 and the second body 408 may or may not be coplanar. The first body 406 and the second body 408 may or may not be coplanar with the front surface 300 of the training aid device 100.

In some examples, putters have hosels that are offset from their putter heads such that they are positioned in front of the putter head. In this regard, a hosel or a shaft of the putter 104 may be come in contact with the body of the training aid device 100 before the putter head 106 comes into contact with the front surface 300. The first body 406 and the second body 408 can be dimensioned to ensure that the putter head 106 contacts the first body 406 and the second body 408 before a hosel or a shaft of the putter 104 contacts any portion of the training aid device 100. The first body 406 and the second body 408 can be customizable to address different putters having different hosel and shaft configurations.

In some implementations, the first body 406 and the second body 408 can house the sensors (for example, the sensors 220, 222, and 224) that can collect various types of data related to the putter head 106. The data can be related to position, time, velocity, acceleration of the putter head 106 during a swing. As will be discussed below, the sensors can additionally and/or alternatively detect contact between the putter head 106 and the first body 406, the second body 408, or the front surface 300.

In some implementations, the first body 406 and the second body 408 can include an attachment element that can attach to a corresponding counterpart of the putter head 106. For example, the first body 406 and the second body 408 can each include a magnetic element that can cause the putter head 106 to “stick” to the training aid device 100 after the ball 102 is struck. The attachment element can advantageously allow users to determine, with reference to the device 100 itself or the front surface 300 of the device 100, whether the ball 102 was struck in the center of percussion of the putter head 106.

The front surface 300 can include a bridge 420 that can connect the first body 406 and the second body 408, as shown in FIG. 4A. The bridge 420 can be coupled to the cover 422 to define a top surface for the channel 402.

The channel 402 of the training aid device 100 can be formed between a first opening 480 and a second opening 482 of the training aid device 100. The first opening 480 can be formed between the first body 406 and the second body 408. The second opening 482 (see FIG. 4B) can be formed between the first base 450 and the second base 460. The first opening 480 and the second opening 482 can be dimensioned and shaped to allow golf balls to travel through. As shown in FIGS. 4A and 4B, the first opening 480 and the second opening 482 can be arch-shaped. The dimensions and the shapes of the first opening 480 and the second opening 482 can be identical. Alternatively, the first opening 480 may be smaller than the second opening 482 to facilitate golf balls to travel through the channel 402 without contacting inner walls 403 of the channel 402. The dimensions (for example, width, height, or diameter) of the channel 402 can be larger than the diameter of the golf ball 102.

The length of the channel 402 can define an axis that represents a desired putting line. The axis (desired putting line)defined by the channel 402 can be perpendicular to the axis (desired putter face angle) defined by the front surface 300. In this regard, ensuring alignment between the putter head 106 and the front surface 300 can assist users to hit the ball 102 along the desired putting line.

FIG. 5 shows another example of the training aid device 100. The training aid device 100 can include openings 500 that can be sloped at a predetermined angle with respect to the ground. In some implementations, the openings 500 can be sloped towards the front surface 300. This can be advantageous because support elements (e.g., pins, rods, etc.) extending through the openings 500 sloped and/or facing towards the front surface 300 can provide additional support (e.g., in a front-rear direction) for the training aid device 100 to remain at its place when struck by putter head 106.

With reference to FIGS. 5, 6A, and 6B, the training aid device 100 can, additionally and/or alternatively, include a first slot 502 and a second slot 506. The first slot 502 and the seconds slot 506 can receive a first gate 600 and a second gate 602, respectively. The slots 502, 504 can extend along a substantial portion of a width of the first body 406 and the second body 408.

The slots 502, 504 can be dimensioned to allow the first gate 600 and the second gate 602 to slide along the widths of the first body 406 and the second body 408, respectively. By adjusting the positions of the first gate 600 and the second gate 602, a distance between the gates 600, 602 can be changed. The distance between the gates can represent the width of the putter head 106 such that the putter head 106 can swing between the gates 600, 602 to contact the first surface 300 of the training aid device 100. By adjusting the positions of the gates 600, 602 and ensuring their putter heads 106 to strike a portion of the first surface 300 between the gates 600, 602, users can improve accuracy of their swing.

For example, as shown in FIG. 6A, the gates 600, 602 can be positioned such that they are a distance x₁ apart from each other. In another example, as shown in FIG. 6B, the gates 600, 602 can be a distance x₂ apart from each other. In some implementations, the distance (for example, distances x₁ and x₂) can define an opening that the ball 102 can travel through. A greater distance between the gates 600, 602 can allow users to strike the ball 102 through the opening, while allowing some degree of mistake. However, smaller distance between the gates 600, 602 can allow users to strike the ball 102 through the opening while allowing less degree of mistake in striking the ball 102. For example, if the ball 102 is struck while the putter head is in an “open” or “closed” position, the ball 102 may not travel between the gates 600, 602.

The gates 600, 602 can be adjusted to allow users to use putters with different putter head width. Putter can have different putter widths, which may result in different locations of the heel and the toe of the putter head. By adjusting the positions of the gates 600, 602, users can improve tactile response provided by the training aid device 100 upon contact between the gates 600, 602 and the putter head 106.

With reference to FIGS. 7A-7C, a velocity and/or angular orientation of the putter head 106 can be determined using one or more sensors (for example, the sensors 220, 222, and 224). The sensors can be positioned along the front surface 300. As the putter head 106 moves towards the ball 102 positioned in front of the training aid device 100, the sensors 220, 222, and 224 can determine when (for example, at what time) the putter head 106 is at a predetermined distance away from the sensors 220, 222, and 224. The distances between the sensors 220, 222, and 224 and the putter head 106 can represent the distance between the training aid device 100 and the putter head 106.

In the example shown in FIG. 7A, the one or more sensors, for example, sensors 220 and 222, can sense when the putter head 106 is positioned a predetermined distance D₁ away from the sensors. In some implementations, the sensor 220 can detect the time the heel 800 (see FIG. 8A) of the putter head 106 is positioned the distance D₁ away from the sensor 220. Similarly, the sensor 222 can determine the time the toe 802 (see FIG. 8A) of the putter head 106 is at distance D₁ away from the sensor 222. On the other hand, the sensor 224 can detect the time the heel 800 or the toe 802 is at a predetermined distance D₂, as shown in FIG. 7B, away from the sensor 224.

Using a delta of the distances D1 and D2 and a delta of time between the time when the heel 800 (or toe 802) of the putter head 106 is at the distance D1 and the time when the heel 800 (or toe 802) of the putter head 106 is at the distance D2, a velocity of the putter head 106 can be determined. An example equation to determine a velocity of the putter 106 is shown below:

$v = \frac{D_{1} - D_{2}}{t_{1} - t_{2}}$

where t₁ is the time when the heel 800(or the toe 802) of the putter head 106 is at the distance D₁, t₂ is the time when the heel 800 (or the toe 802) of the putter head 106 is at the distance D₂, and v is the velocity of the putter head 106.

Alternatively, the velocity of the putter head 106 can be calculated using a sensor to determine positions of the putter head 106 at different timestamps. For example, a sensor can determine that at t₁, the putter head 106 was at a distance D₁ away from the training aid device and at t₂, the putter head 106 was at a distance D₂ away from the training aid device. In this regard, the velocity of the putter head 106 can be calculated using the same equation as shown above.

Additionally, an angular orientation of the putter head 106 can be determined by comparing time when the heel 800 and the toe 802 of the putter head 106 is at the distance D₁ away from the sensors 220 and 222. FIGS. 8A-8C show the putter head 106 in different angular orientations with respect to the training aid device 100. The angular orientation of the putter head 106 can be characterized by an angle between an axis 700 and an axis perpendicular to the surface of the putter head 106. The axis 700 can represent the desired line of travel of the putter head 106. Such axis perpendicular to the surface of the putter head 106 is shown as an axis 804 in FIG. 8B and as axis 806 in FIG. 8C.

As shown in FIG. 8A, when the putter head 106 is “square” with the training aid device 100, the axis perpendicular to the surface of the putter head is aligned with the axis 700. When the putter head is not “square” with the training aid device 100, it can be either “open” or “closed” depending on the angular orientation of the putter head 106. If the toe 802 of the putter head 106 is travelling behind the heel 800 of the putter head 106, the putter head is “open” configuration. On the other hand, if the heel 800 of the putter head 106 is travelling behind the toe 802 of the putter head 106, the putter head 106 is in “closed” configuration.

With respect to FIG. 8D, the angular orientation (that is, angle θ) of the putter head 106 can be calculated using the velocity of the putter head 106, distance between the sensors that detect positions of the heel 800 and the toe 802 of the putter head 106, and a delta of time between the time the heel 800 is at a predetermined distance (for example, distance D₁) away from the training aid device 100 and the time the toe 802 is at the same predetermined distance away from the training aid device 100. For example, the angular orientation of the putter head 106 can be calculated using equations shown below:

$\theta = {\tan^{- 1}\frac{a}{b}}$ a = v * t₁ − t₂

where v is the velocity of the putter head 106, t₁ is the time the heel is at a predetermined distance away from the training aid device 100, and t₂ is the time the toe 802 is at a predetermined distance away from the training aid device 100.

In some implementations, the training aid device 100 can include one or more sensors that can detect contact between the putter head 106 and the training aid device 100. After the putter head 106 is brought into contact with the ball 102, the putter head 106 can continue to move towards and contact the training aid device 100. For example, the putter head 106 can be in an orientation depicted in FIG. 8D such that an area around the sensor 220 comes into contact with the putter head 106 prior to an area around the sensor 222. If the sensor 220 detects contact before the sensor 222 does, it can indicate that the putter head 106 was not “square” with the training aid device 100. In contrast, if the sensor 220 and the sensor 222 detects contact substantially around the same time, it can indicate that the putter head 106 was “square” with the training aid device 100.

Additionally and/or alternatively, users can determine whether the putter head 106 was aligned with the desired putting line from a contact between the front surface 300 and the putter head 106. As discussed above, if the toe and the heel of the putter head 106 contact the front surface 300 at the same time, the putter head 106 was “square” with the training aid device 100. On the other than, if the toe and the heel of the putter head 106 do not contact the front surface 300 at the same time, the putter head 106 was not “square” with the training aid device 100.

The training aid device 100 can include a rod 900, as shown in FIG. 9. The rod 900 can serve as an aiming rod that can provide a desired putting line for a user. In some implementations, the openings 410, 412 can be dimensioned to receive the rod 900. The rod 900 extend from either of the opening 410 or the opening 412, or both. The position of the rod 900 can be fixed or adjustable with respect to the openings 410, 412.

Additionally, the rod 900 can permit a user to determine whether the ball 102 was struck at the center of percussion of the putter head 106. The rod 900 can be made in various types of materials including, but not limited to, plastic, rubber, metal, wood, or any other flexible substances. The rod 900 can include one or more markings 902 along its length. In some implementations, the markings 902 can be periodically and/or randomly spaced apart from each other. The markings 902 can be in different color compared to the rod 900 so that the markings 902can be easily seen by a user.

The rod 900 can extend and bisect the training aid device 100 and the channel 402. Additionally, the rod 900 can be placed within the training aid device 100 such that the rod 900, when looked from above, defines a desired line of travel for the ball 102 after being struck by the putter head 106.

FIG. 10 shows an example method 1000 for calculating a putter head velocity and a putter head angular orientation. At step 1002, a first sensor is used to collect a first data associated with the putter head 106 as it moves towards the training aid device 100. The first sensor can be either one of the sensors 220, 222, and 224 as described above. The first sensor can be positioned about either the first body 406 or the second body 408. In some implementations, the first sensor can be positioned about the front surface 300 of the training aid device 100. The first sensor can be a distance measuring sensor.

The first data can include time-based data. For example, the first data can include when a portion of the putter head 106 is positioned at a predetermined distance (for example, distance D₁) away from the first sensor. The portion of the putter head 106 can be the heel 800, the toe 802, or any other portion of the putter head 106. Alternatively, the first data can include spatial data. In some implementations, the first sensor can determine the distance between the first sensor and a portion (for example, heel 800, the toe 802, or any other portion) of the putter head 106. The first data can include both the time-based data and the spatial-based data.

At step 1004, a second sensor can collect a second data associated with the putter head 106. The second data can be associated with the same portion of the putter head 106 as the first data. For example, both the second data and the first data can be associated with the heel 800, the toe 802, or some other portion of the putter head 106. In some implementations, the second data can be associated with a different portion of the putter head 106 as the first data. For example, the first data can be associated with the heel 800 while the second data can be associated with the toe 802.

At step 1006, a third sensor can collect a third data associated with the putter head 106. The third data can be associated with the same or a different portion of the putter head 106 as the first data and the second data. For example, the third data and the first data can be associated with the heel 800 (or the toe 802) while the second data can be associated with the toe 802 (or the heel 800). In another example, the third data and the second data can be associated with the heel 800 (or the toe 02) while the first data can be associated with the toe 802 (or the heel 800). The third sensor can be placed on the training aid device 100 such that it collects data associated with a middle portion of the putter head 106. At step 1008, the processor 200 of the training aid device 100 can calculate the velocity and/or the angular orientation of the putter head 106 as previously discussed above. Not all of the first data, the second data, and the third data may be used to calculate the velocity and/or angular orientation of the putter head 106. In some implementations, a single sensor may be used to calculate the velocity of the putter head as previously discussed above.

FIG. 11 shows another example method of determining the velocity and/or the angular orientation of the putter head 106. At step 1102, a first data associated with the putter head 106 is collected using a first sensor. As discussed above, the first sensor can be any one of the sensors 220, 222, and 224 discussed earlier. The first data can include spatial-related or time-related data, or both. At step 1104, a second data associated with the putter head 106 is collected using a second sensor. At step 1106, a third data associated with the putter head 106 is collected using a third sensor. Both the second data and the third data can include spatial-related data or time-related data, or both. The first data, the second data, and the third data can be sent to the processor 200 of the training aid device 100.

At step 1108, a putter head velocity is calculated using the first data (or the second data) and the third data. As previously discussed above, the angular orientation of the putter head 106 can be determined by collecting spatial-based and time-based data of different portions of the putter head 106. The different portions can be the heel 800 and the toe 802 of the putter head 106. In some implementations, data associated with a different portion of the putter head 106 other than the heel 800 and the toe 802 can be used to determine the angular orientation.

FIG. 12 shows an example method 1200 for determining angular orientation of the putter head 106 using time-based data. At step 1202, a first sensor collects a first timestamp. The first timestamp can be the time at which a first portion of the putter head 106 is at a predetermined distance (for example, distance D1) from the first sensor or the training aid device 100. The first portion of the putter head 106 can be the heel 800, the toe 802, or some other portion of the putter head 106. At step 1204, a second sensor collects a second timestamp. The second timestamp can be the time at which a second portion of the putter head 106 is at the predetermine distance from the second sensor or the training aid device 100. The second portion can be different from the first portion.

At step 1206, the first timestamp is compared with the second timestamp. At step 1208, the processor 200 can determine whether the first timestamp is greater than the second timestamp. In other words, the processor 200 determines whether the first portion (associated with the first timestamp) is travelling behind the second portion (associated with the second timestamp). Assuming that the first portion is the toe 802 and the second portion is the heel 800, if the first timestamp is greater than the second timestamp, the processor 200 can determines that putter head is in an “open” configuration at step 1210 (that is, the toe 802 is travelling behind the heel 800). If the first timestamp is not greater than the second timestamp, then the processor 200 determines whether the first timestamp is less than the second timestamp at step 1212. Assuming that the first portion is the toe 802 and the second portion is the heel 800, if the first timestamp is less than the second timestamp, the processor 200 can determines that putter head is in an “closed” configuration at step 1214 (that is, the toe 802 is travelling in front of the heel 800). If the first timestamp is not less than the second timestamp, the processor 200 can determine that the putter head 106 is “square” with the front surface 300 of the training aid device 100 at step 1216.
